IMPROVEMENT IN MACHINES FOR PAPEEING PINS.

TO ALL WI-IOM IT MAY CONCERN: i

Be it known that I, THADDEUS FOWLER, of Seymour, in the county of New Haven, and State of Connecticut, have invented, made, and applied to'use, a certain new and useful Improvement in Pin-Sticking Machinery; and I do hereby declare the following to'be a full, clear, and exact description of the said invention, reference being had lto the annexed drawing, making part of this speciiicationUvherein-f- Figure I is a plan of my said machine.

Figure 2 is a vertical section of the same at the line :v zu.

Figure 3 is a vertical section of the said machine at the line m z.

Figure 4 is a sectional plan in larger size of thebase of the conductors, showing the mode in which one line of p ins is out off from the others; and

Figure 5 is a similar view, showing how the lines of pins in the conductors are sustained, and the line that is cut oh" allowed to drop.

Similar marks of reference denote the sameparts.

VIrIeretofore difficulty hasbeen experienced in pin-sticking machines from the pins becoming obstructed, in consequence of any slight crook or bend, and hence the further movements of the machine sometimes bend the pin'much more and prevent Vthe machine working.

The object of my invention is to separate a row of pins at a time from the ends ofthe conductors, and stick them in such a manner that any crooked pin or imperfect pinwill not check or obstruct the operation of the machine, but will fall through. l

My invention consists in a spring cut-off, formed of a series of points that pass in between the first and second pins of the rows of pins in the conductors, and hold up all but the rst row, which is allowed to fall into the sticking-apparatus, consisting ina series of grooves in front of which is a spring-door that is swung down by the action of a rake that enters the Ygrooves and forces the 'pins down through the paper, as it -is'in the crlmpingjaws.

In the drawing, a is a frame carrying the mechanism; b isa. series of conductors, formed in any usua manner, and supplied with pins in any known or convenient way, Below the ends of the conductors 6 is an inclined breast, e, having grooves in its surface formed between plates that extend down from the lower ends of the bars forming the conductors or in any other convenient manner, and at the lower end of this inclined` grooved breastc is the stationary crimpingljaw cZ, the stri-p of paper e, into which the pins are stuck, passing in 'between thebreast c and jaw d, and passing down to any feeding-device for drawing the paper along periodically".

The moving erimping-jawf-is on van arm, f', fitted to swing on the centre l, and is operated at the right time by thel cam g on the shaft h, and drawn back by the spring 2, or other convenient mechanism. Upon theupper edge of the jaw f is the door z', hinged at its lower edge, and thrown up bya spring, 3, so'as to close against ,the grooves in the inclined breast c, and prevent the pins falling out of` said grooves as they are dropped, as hereafter specified; 4 is an inclined curved arm on the door t', that extends out beneath the rake k, and said rake 7c is formed with'teeth'corresponding to the grooves in the breast c, and is set upon slide-bars 5, that are Amortised near their lower` ends to slide upon pins 6, that project from a vcross-har, 15, near the base of the arm f.. 7 7 are springs acting to draw the rake 7c up, and 8 8 are springs that act to draw the rake away from the breast e. Z Z are cams on the shaft L, that act at the proper time to force the teeth ofthe rake k back into 'the V grooves in the breast c, and pins 9 9 on thcse'carns Z, acting upon toe-pieces 10 on the.bars 5, draw down the rake, sticking the pins into the crimped paper. This movement-of the rakeA swings back the door i into the position shown in fig. 2, and as the pins 9 clear the toes I0, and the rake c is drawn up again by the springs 7, the'door z' is turned up again by its spring 3, and closed. A bar, n, is iittedito slide -below the ends of the con ductors b, and in is moved at the right time bythe leveric and cam pj From this bar project cut-off hooks s s, seen in larger size in figs. 4 and 5. These occupy'a horizontal groove across the ends of the conductors, alittle below their upper surfaces. 7- isa stop-bar, ittedto be moved up to the lower ends ofthe conductors, or drawn .flown from the samcby the action `ot` the levers g, cams t, and springs 11.

It will new be understood that when the spring cut-offs s stand in the position of fig. 4, the pins in the conduetors rest against the edge of the bar 7', and hang by their heads; the spring cut-offs are then nioved, their points enter between the bodies ot' the pins in the first :intl second row, preventing the pins from eomin,r flown the conductors while the hor 1' is drawn back, and drops the lowest row of pins, and they fall agoinst the plate u, and thence pass into the grooves in the inclined breast c. The reverse movements ofthe spring eut-offs s :1nd bar r allow another row of pins toeome into position to be eut o' as aforesaid.

What I claim, and desire to secure by Letters Patent, is l 1. The pointed eut-offs s, applied at the lower ends of the conductors, in combination with the stop-bar r, substantially as and for the purposes set forth.

2. The grooved breast c, and spring-door t', in combination with the rake 7c, substantially. as and for the purposes set forth.

In witness whereof, I have hereunto set my signature, this twenty-sixth day of April, A. D. 1867.

THADDEUS FOWLER.
